| Project Engineering | Hydraulic, electrical, structural, lighting and control-system design coordinated in one project package. | General arrangement drawings, hydraulic calculations, load schedules, cable plans and control architecture. | Reduces interface risks between civil works, pumps, nozzles, lighting and automation systems. | Essential |
| Water Feature Control | Programmable synchronization of pumps, valves, underwater lights, audio and show scenes. | Demonstration video, sequence list, control-system specification and operator interface sample. | Enables repeatable performances, scheduled shows and easier maintenance. | Essential |
| Lighting Protection | Underwater lighting specified with an appropriate ingress-protection rating; IP68 is commonly used for equipment designed for continuous immersion. | Product datasheets, independent test reports and installation-depth limitations. | Protects luminaires from water ingress, corrosion and premature electrical failure. | Essential |
| Electrical Safety | Clear separation of extra-low-voltage underwater circuits, protection devices, grounding and residual-current protection where required by local codes. | Single-line diagrams, protection calculations, conformity documents and commissioning records. | Public plazas require strong protection against shock, leakage and equipment faults. | Essential |
| Music and Show Integration | Time-coded show playback with adjustable audio, water and lighting parameters. | Supported audio formats, synchronization method, sample show files and licensing terms. | Improves visual timing and allows cultural, seasonal or event-based programming. | High |
| Pump and Nozzle Efficiency | Pump selection matched to required flow, head, duty cycle, nozzle pattern and water-quality conditions. | Pump curves, nozzle performance charts, energy calculations and duty/standby philosophy. | Directly affects jet height, choreography stability, electricity use and operating cost. | High |
| Water Treatment | Filtration, chemical dosing, water-level control and maintenance procedures designed for recirculating water. | Water-treatment schematic, filtration capacity, cleaning schedule and recommended water parameters. | Controls clogging, scaling, algae growth and nozzle-performance loss. | High |
| Outdoor Durability | Materials and finishes selected for continuous outdoor exposure, UV radiation, humidity and chemical contact. | Material grades, coating specifications, corrosion-resistance details and environmental operating limits. | Plaza installations face weather, public use and frequent operating cycles. | High |
| Acoustic Performance | Audio system designed around audience coverage, ambient noise, intelligibility and local noise limits. | Sound-pressure calculations, speaker layout, limiter settings and local compliance approach. | Maintains show quality while minimizing disturbance to nearby residents and businesses. | Medium |
| Installation and Commissioning | Supplier-supported installation, dry testing, wet testing, choreography adjustment and operator training. | Method statement, commissioning checklist, training agenda and acceptance-test procedure. | Professional commissioning helps achieve the specified jet, lighting and synchronization results. | High |
| After-Sales Service | Documented spare-parts plan, remote troubleshooting, maintenance training and defined response times. | Warranty terms, spare-parts list, service-level agreement and troubleshooting manuals. | Reduces downtime and supports long-term operation after handover. | High |
| International Compliance | Equipment documentation aligned with the destination market’s electrical, machinery, EMC, safety and construction requirements. | Declarations of conformity, test reports, technical files and destination-country approvals where applicable. | Supports permitting, import clearance, insurance review and project acceptance. | Essential |
| Lifecycle Cost | Evaluation based on purchase price, installation, energy, water treatment, consumables, maintenance and replacement parts. | Total-cost-of-ownership model with estimated annual energy and maintenance requirements. | The lowest initial quotation may not provide the lowest long-term operating cost. | Medium |
